Engineered for advanced to expert skiers, the K2 Cortex 120 BOA® delivers pro-level performance with a dialed-in fit that adapts at the push of a button. Featuring a dual BOA® Fit System (shell + cuff), this boot provides micro-adjustable control for a snug, locked-in feel—no pressure points, no fuss. Built on a low-volume 96–98 mm MultiFIT last and fitted with a 120 flex TPU shell and cuff, the Cortex 120 balances stiffness with comfort. It’s equipped with the EliteFit Sport liner, FastFIT instep, GripWalk soles, and an Energy Bolt Spine—all working to ensure precision, power, and walkability. Fully heat-moldable and fully customizable, this boot is ready to elevate your all-mountain performance.

Features

  • Dual BOA® Fit System (shell & cuff): micro-adjustable dials allow independent tuning of upper and lower zones for perfect pressure distribution
  • 120 Flex Rating: stiff and responsive—designed for aggressive carving, big-mountain lines, and fast terrain
  • Low-Volume MultiFIT Shell (96–98 mm last): precision last for a locked-in fit on narrower feet
  • EliteFit Sport Liner: heat-moldable, full-lace liner with Ski Edge Sensitivity shims for enhanced edge control
  • FastFIT Instep & GripWalk Soles: softer TPU instep eases foot entry, while GripWalk soles provide traction off the snow
  • Energy Bolt Spine & Dual Cuff Alignment: rear cuff support ensures precise forward flex; adjustable alignment tailors stance
  • Non-Elastic Cam Booster Strap: locks down power with responsive snugness
